Cov LEDs yog qhov yooj yim tsim nyog ib yam nkaus. Peb yuav siv Adafruit Neopixel lub tsev qiv ntawv. Tus kheej, lub tsev qiv ntawv NeoPixel zoo ib yam rau kev ua haujlwm hauv Kev Ua Haujlwm, yog tias koj tau ua haujlwm nyob rau ntawd.

Muaj thawj qhov teeb tsa teeb tsa, hais txog lub tsev qiv ntawv twg peb tab tom siv, thiab teeb tsa kab lus uas hais tias muaj pes tsawg LEDs nyob ntawm tus pin, tus pin yog rau cov ntaub ntawv, thiab nws tau npaj li cas. Qhov no ua tiav nrog qhov piv txwv zoo li Adafruit_NeoPixel strip = Adafruit_NeoPixel (6, 10, NEO_GRB + NEO_KHZ800); Qhov no piav qhia tias muaj 6 LEDs, tus lej yog tus lej tus lej 10, thiab qhov ntawd yog siv NEO_GRB + NEO_KZH800 hom ntawm cov kab lus hais tau. Feem ntau qhov kev sib cav zaum kawg tsis tas yuav kov, cov hlua LED uas kuv siv tsis xav tau qhov hloov pauv.

Tom qab ntawd koj xav tau strip.begin (); muaj nuj nqi qhia tias koj tau npaj pib siv lawv. Tsis muaj dab tsi xav tau nyob hauv cov kab zauv.

Thaum koj muaj qhov ntawd, koj tuaj yeem hu cov haujlwm sib txawv nrog cov hlua. [Ua haujlwm]

Ib qho uas koj yuav tsum paub yog strip.setPixelColour. Qhov no muaj 4 lub luag haujlwm hauv cov kab ke. Koj muaj LED nyob hauv 'array' ntawm LEDs (nco ntsoov, Arrays pib ntawm 0) thiab qhov sib xws liab, Ntsuab, thiab Xiav qhov tseem ceeb ntawm 0-255. Qhov no yuav tso cai rau koj los sib xyaw qhov xav tau Liab Ntsuab thiab Xiav kom tau txais xim uas koj xav tau. Cov cai yuav tsum zoo li: strip.setPixelColour (0, 0, 255, 255); yog tias koj xav tau xim ntsuab ntawm thawj LED.

LED tseem yuav tsum tau xa cov ntaub ntawv ntawd, uas yog dab tsi strip.show (); ua. Nws yuav hloov kho cov pixels tom qab koj tau hloov qee yam nrog lawv. Tsis muaj dab tsi xav tau mus rau hauv cov kab zauv.

Cov cai yuav tsum zoo li:

// Code Ua los ntawm Foster Phillips

#include Adafruit_NeoPixel.h #define PIN 10 #define Num 6 Adafruit_NeoPixel strip = Adafruit_NeoPixel (Num, PIN, NEO_GRB + NEO_KHZ800); teeb tsa tsis muaj dabtsis () {strip.begin (); strip.show (); } void loop () {strip.setPixelColor (0, 255, 0, 0); strip.setPixelColor (1, 255, 0, 0); strip.setPixelColor (2, 255, 0, 0); strip.setPixelColor (4, 255, 0, 0); strip.setPixelColor (3, 0, 0, 255); strip.setPixelColor (5, 0, 0, 255); strip.show (); }

Cov ntaub ntawv ntxiv tuaj yeem pom ntawm no.

Kauj ruam 11: Sib sau ua ke

Qhov no tej zaum yog cov kauj ruam yooj yim tshaj plaws, thiab txias tshaj plaws.

Pib los ntawm kev tso thiab swb hauv Pro Micro mus rau rooj plaub kaw. Muab nws tso rau hauv qhov chaw nrog qee cov kua nplaum kub.

Cov ntaub ntawv/kaw tau tsim los kom koj tuaj yeem sab ntawm lub phaj hloov pauv thiab LED phaj hauv. Tsuas yog xaub nws, thiab nyob ntawm seb koj luam nws li cas, koj yuav xav tau ntawv lossis txiav sab hauv ntawm cov swb kom tshem qee cov yas yas.

Tom qab ntawd, tau txais koj cov ntsia hlau thiab tsuas yog jam nws rau hauv thiab ua koj tus kheej lub qhov ntsia hlau. Kuv tsis muaj cov xov tshwj xeeb tshwj xeeb thaum kuv tsim cov ntawv, yog li kuv tsuas yog ua lub qhov ntxhib me me ntawm cov ntsia hlau thiab ntsia nws hauv kuv tus kheej. Cua sov nws nrog lub teeb yuav pab tsim nws rau cov ntsia hlau uas koj xav tau, thiab feem ntau ntxiv dag zog rau txheej. Nco ntsoov tsis thawb ntau dhau ntawm cov ntsia hlau, lossis koj tuaj yeem hle lub taub hau. Kuv siv Allen qhov tseem ceeb screws los txo qhov kev pheej hmoo no.

Tom qab ntawd cia li thawb lub khawm tseem ceeb rau cov yuam sij. Tom qab ntawd nws zoo nkauj npaum li cas! Kuv qhov version ntawm Arrow Key Macropad tau ua tiav!

Kauj Ruam 12: Koj Tus Kheej Kev Txhim Kho

Tam sim no koj paub yuav ua li cas rau kuv version, koj tuaj yeem ua koj tus kheej! Keyboards tuaj yeem sib cav txog kev qhia koj tus kheej, yog li tsuas yog muaj lwm tus tsim qhov tsis lom zem tshwj tsis yog koj hloov kho kom haum koj! Muaj ntau qhov kev txhim kho koj tuaj yeem ua tau! Nov yog qee qhov kev txhim kho uas kuv xav ntxiv lossis xav txog!

• Program Tetris thiab lwm yam kev ua si yooj yim
• Ua nws bluetooth
• Tso cai rau nws nyeem cov ntaub ntawv los ntawm cov duab swb thiab tso nws ib qho OLED (Qhia tus lej swb thiab lub npe ntawm swb)
